● Zero standby power consumption with low system cost
(< 5mW at 230VAC when output USB cable is detached
in a typical 25W USB PD travel adapter) - iW9860
● Lowest BOM cost with < 20mW no-load power
consumption by removing the need for external startup
DFET - iW9861
● Supports single-layer PCB design to reduce total
system cost
● Supports Rapid Charge adapters applications of
15W-63W and other power profiles
● Uses Renesas’ patented switching modes [adaptive
quasi-resonant (QR) operation and adaptive multi-mode
control (MMC)] and continuous conduction mode (CCM)
x Improves efficiency and eliminate audible noise
x Enables optimization for size, efficiency and EMI
performance
● Supports voltage sensing with dual polarity of VVCC
auxiliary winding for improving EMI and simplifying
transformer design
● Intelligent gate drive control to minimize driving loop
and eliminate high voltage capacitor
● Max switching frequency range - 70kHz to 130kHz
(by product option - see Section 7)
● Supports constant-voltage (CV) and constant-current
(CC) regulation in fine steps using secondary-side
regulation (SSR) control
● Built-in single-point fault protections against AC line
voltage brown-in, brown-out, output short-circuit,
output over-voltage, and optocoupler failure
● User adjustable internal OTP threshold for various
thermal requirements
● 6-lead SOT-23 package supports compact power supply design
